Hi Patrick

I tried this and did not really help.

I thought it was correct but I tried this all the way back to 1.3.1 and did not address the situation..

Still the same error...

Is there a global way to set the compiler to use an earlier JVM

Hi All

I have been running an app on Tiger server + latest Webobjects run environment and recently updated development to the latest XCode 2.3

Now I have tried to build an existing running app and when I try to start it I get a error - this runs on the client but problem is when I upload to the server:

java.lang.UnsupportedClassVersionError: Application (Unsupported major.minor version 49.0)


Any ideas what this could be?

The JVM on the target machine has encountered a classfile in JDK 1.5 format. This most likely means you built using the JDK 1.5 compiler, which became the default after a recent software update, and the machine on which you are trying to deploy is still using the 1.4.2 JRE. Since WebObjects has not (yet?) been qualified for Java 5, you are best off rebuilding using JDK 1.4*, see also http:// docs.info.apple.com/article.html?artnum=75505 , as per Cliff Tuel's email "Re: Java 1.5 & WO?' of Tue, 25 Apr 2006 16:07:21 -0700 (PDT).
